Perhaps you should try some spelling variations:
largest decrease » larger decrease (Expand Search), marked decrease (Expand Search)
values decrease » values increased (Expand Search)
marker decrease » marked decrease (Expand Search), larger decrease (Expand Search), marked increase (Expand Search)
c largest » _ largest (Expand Search), c large (Expand Search)
i values » _ values (Expand Search)
a marker » _ marker (Expand Search), _ markers (Expand Search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( i values decrease ) OR ( c largest decrease ))) OR ( a marker decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (((( i values decrease ) OR ( c largest decrease ))) OR ( a marker decrease ))*.
